An eye-conditioning and eyesight-improving device which can be placed in fro nt of the eye and fixed there temporarily, and which has a carrying body suppli ed with at least two apertures situated in the environment of the axes of the t wo eyes and adjusting devices having a primary disc, a secondary disc, and a revolving treatment disc connected to either the primary or secondary disc, having a group of treatment forms consisting of eyehole apertures that can b e turned so that they are in front of the optical axis setting apertures. His group is supplemented with a closing member (43) that is opaque to light and is regularly fitted between the eyehole apertures (41, 42), the distance (t) between the edges of the eyehole apertures (41, 42) neighbouring the closing member (43) on the pitch circle (32) is larger or the same as the chord (50) length (h) measured between the circumference (21c) of the optical axis setting aperture (21a) and the points of intersection (M1, M2) of the pitch circle (32).
